Abstract
The present specification provides a method for transmitting data of a machine type communication (MTC) device. The method for transmitting data of an MTC device comprises the steps of: receiving a mobility management (MM) latency timer from a mobility management entity within a network; operating the MM latency timer; determining whether data to be transmitted is generated before the expiration of the MM latency timer; and transmitting the data to be transmitted through an uplink NAS message even though the MM latency timer has not expired when the data to be transmitted is generated.
Claims12
A method for transmitting data of a machine type communication (MTC) device, the method comprising:
- receiving, by the MTC device, a mobility management (MM) back-off timer and a session management (SM) back-off timer;
- starting the MM back-off timer and the SM back-off timer;
- determining whether data to be transmitted is pending before the MM back-off timer expires;
- generating a short message service (SMS) based message including the data, when the SM back-off timer is not running or expires and when the MM back-off timer is running;
- and
- transmitting the SMS message when the SM back-off timer is not running and when the MM back-off timer is running,
- wherein a MM request message is not allowed to be transmitted until the MM back-off timer expires or is stopped, and
- wherein the SMS based message and a SM request message are not allowed to be transmitted until the SM back-off timer expires or is stopped.
A machine type communication (MTC) device comprising:
- a reception unit to receive a mobility management (MM) back-off timer and a session management (SM) back-off timer;
- a processor that:
- starts the MM back-off timer and the SM back-off timer,
- determines whether data to transmit is pending before the MM back-off timer expires, and
- generates a short message service (SMS) based message including the data,
- when the SM back-off timer is not running or expires and when the MM back-off timer is running;
- and
- a transmission unit to transmit the SMS message when the SM back-off timer is not running and when the MM back-off timer is running,
- wherein a MM request message is not allowed to be transmitted until the MM back-off timer expires or is stopped, and
- wherein the SMS based message and a SM request message are not allowed to be transmitted until the SM back-off timer expires or is stopped.
